(Specification)Standard Specification for Aggregate for Masonry Mortar
Standard Specification for Aggregate for Masonry Mortar
ABSTRACT
This specification covers aggregate for use in masonry mortar. Aggregate for use in masonry mortar shall consist of natural sand or manufactured sand. Manufactured sand is the product obtained by crushing stone, gravel, or air-cooled iron blast-furnace slag specially processed to ensure suitable gradation. Aggregate for use in masonry mortar shall be graded within the limits prescribed. The amount of deleterious substances in aggregate for masonry mortar, each determined on independent samples complying with the grading requirements. Except as herein provided, aggregate subjected to five cycles of the soundness test shall show a loss, weighted in accordance with the grading of a sample complying with the limitations set forth. A density test shall be performed. The air content of mortars shall be calculated.
SCOPE
1.1 This specification covers aggregate for use in masonry mortar.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
